Last week, MIT Technology Review brought together some of the world's sharpest minds dedicated to developing the technologies that are changing the way we live. EmTech, our annual flagship event covering cutting-edge developments and global trends, heard from experts working in fields as diverse as space commercialization to CRISPR gene editing, helping to set the agenda for the year ahead, and beyond. A massive thank you to everyone who attended in person and online! Kiran Musunuru, a top American cardiologist, is pioneering the use of gene editing to treat heart disease. He sat down with Antonio Regalado, our senior biotech writer, to discuss the clinical trial he's been overseeing to assess whether tweaking a cholesterol-regulating gene could help to prevent future deaths from heart disease.
